I have read some comments about the PM-20/LV ect but not much on the PM-25 vs G0704 subject. I'm curious as to any advantages the PM-25 might offer as I do not have access to any equipment to fix ways ect since I am just starting out.

Also curious if I should go single or double ballnut? I'd like the most precision possible but I also hope to extend the Y to 9" in the future. Finally, I am looking at the KL-5056 steppers for X & Y and not sure if I should spring for the KL-5056D version after seeing cruddcnc's parts finish with them which is about what I'm aiming for in the long run.

Thanks and sorry if this has been covered. I searched google quite a bit before posting but it's possible I'm too newb to know the right way to ask these questions :cheers:
